Introduction to Remote Sensing

Introduction to Remote Sensing. Instructor: Prof. Arun K. Saraf, Department of Earth Sciences, IIT Roorkee. The proposed course provides basic understanding about satellite based Remote Sensing technology. Presently, remote sensing datasets available from various earth orbiting satellites are being used extensively in various domains including in civil engineering, water resources, earth sciences, transportation engineering, navigation etc. Google Earth has further made access to high spatial resolution remote sensing data available to non-experts with great ease.
